This built was started two years ago and was interupted by me becoming the club secretary. In the previous Forum I did start a built thread but will start again with what was published until then (Pdf file ) and then add pictures I took during me built restart.

Jilles,

When gluing with this hot pva method, if you dampen both surfaces immediately before applying the iron you get a much stronger bond.

Alternatively make the joint when the pva has just gone clear but before it has dried out fully.

Hi Jilles,

A lovely build thanks for sharing with us.

What is the advantage of putting the PVA on the wood/drying/ironing as opposed to using wet PVA and clamping?

Is glassing a compound fuselage difficult as I see the nose has not been glassed. I take it your using expoxy ?

Well done Jilles.
She is looking very nice. I look forward to seeing the finished model.

The advantage of the PVA / ironing method is that no clamping is needed at all. The bond is instant as soon as the PVA is heated by the iron and this makes it easy to cover difficult areas or tight radii where it may not be possible to easily clamp the wood whilst the glue dries.

John,

Thanks for explanation. I will try out this method in future.
